You did not mention the kind of car. Check the fuses and relay to be sure you have power. Also you have a blower motor resistor and the fan motor. Grounds are just as important as the power source.
Is this a 2003 Pontiac Bonneville? I need this answered for this year and make.
You cant
Replace it
ac is making fan run more
assuming this is Home AC question - speed up the AC fan speed
Defective fan thermal relay switch.
with a new compressor is a good place to look and see if it's working then see if the fan to blow it is still working you fix it with a new ac compressor pulley and recharge the freon in the car
It depends on the motor. The fan is driven by an electric motor, and it can use a dc motor (as in a car) or an ac motor (as in a house). They are not interchangeable.
get in the car when it is cold, turn on the ac, then check under the hood. the fan that is not spinning when the car is cold is the cooling fan
If you don't have power to your heater or ac fan, it could be a fuse or a relay. You should check your owner's manual to determine which fuse or relay affects your fan.
Check the temp sensor. Also, if the AC compressor is on the radiator fan will be on, so turn off the defroster and the AC.
